摘　　要：含多能源站的区域综合能源系统(district integrated energy system,DIES)具有多层级、多运营主体的特征,难以采用传统的集中式方法优化调度。为保证不同运营主体的利益与隐私,该文提出了一种考虑阶梯型碳交易机制的区域电-热综合能源系统分布协同调度方法。首先分析运营主体特性,构建计及热网动态特性和站间互济的综合能源系统模型。在此基础上,构建综合能源系统双层优化调度模型:在系统调度层中,以运营商的经济性和低碳性为目标;在站间调度层中,能源站根据系统调度层的优化结果,调整自身调度策略以实现利益最大化。最后,采用目标级联分析算法(analysis target cascade,ATC)实现交互变量的解耦,并提出了层内迭代、层间互联的求解方法。仿真结果表明,所提调度方法可提高系统运行的低碳经济水平,并通过分布优化兼顾各主体的利益诉求,更满足实际调度需求。The district integrated energy system(DIES) with multiple energy stations has the characteristics of having multi-level and multi-operators, so it is challenging to adopt the traditional centralized method to optimize the dispatching. To ensure the interests and privacy of different operators, a distributed coordinated dispatching for district integrated electric-thermal energy systems considering the ladder-type carbon trading mechanism is proposed. Firstly, the characteristics of operators are analyzed, and an integrated energy system model is constructed considering the dynamic characteristics of the heat supply network and the power interaction between energy stations. On this basis, a bi-level optimal dispatch model of an integrated energy system is built: In the system dispatching layer, the economy and low-carbon characteristics are taken as the goals;In the energy station dispatching layer, the energy station adjusts its scheduling strategy to maximize the benefits according to the optimization results of the system dispatching layer. The analysis target cascade(ATC) algorithm decouples the interaction variables, and a solution is proposed to achieve the intra-layer iteration and inter-layer interconnection. The simulation results verify that the proposed distributed coordinated dispatching method improves the low-carbon economic level of the DIES. By taking into account the interests of each operator through the distribution optimization, it better meets the actual scheduling needs.
